Title: Hydraulically driven oil well pump
Inventor: SMITH WINSTON
IPC: F04D13/04
Filed: 1997-07-04
Abstract: A down hole rotary pump in a well is driven by a down hole hydraulic motor. The motor is mounted in the production string using a motor mount. The motor mount is ported to allow the flow of produced fluid past the motor and through the mount to the production tubing above the motor. This arrangement eliminates the sucker rod drive that causes power loss and tubing wear and mitigates problems in completing directional and deviated wells.

Patent CA-2210666-A1 (CA)
Title: Cable terminator
Inventor: DEAN MICHAEL R
IPC: H01R24/44
Filed: 1997-07-16
Abstract: The present invention comprises a terminator which features an internal termination resistor and capacitor mounted on a substrate which is in electrical and mechanical communication with a center terminal pin at one end, and the connector body at the other end. The body of the terminator is grounded via the connection of the terminator to a cooperating connector.   The present invention includes a support insulator which protects the internal components of the terminator by preventing transmission of tensile, torsional, and bending stresses through the terminal into the termination chip assembly.  The stresses are absorbed by means of a supportive insulator which frictionally supports a textured section of the center terminal within the terminator.   The stresses typically occur during installation or removal of the terminator to or from a connector.  With the present invention it is possible to twist and bend the metal terminal of the terminator to the point of fracture without damaging the termination chip. Additionally, the performance of the terminator is improved since the connection from the substrate of the termination chip to the terminator body has been enhanced, thereby reducing the high levels of intermodulation distortion associated with prior art terminators.

Title: Pressure sensitive cohesive patterns for z fold and c fold business forms
Inventor: CHAPPELL THEODORE M
IPC: B65D27/10
Filed: 1998-01-13
Abstract: In the production of mailer type business forms, particularly from a web in a roll configuration having a plurality of business form intermediates, with pressure sensitive cohesive, the problem of cohesive blocking (sticking together) at inopportune times is avoided by spacing substantially linear patterns of the cohesive disposed in the detachable side edges of the intermediates so that when the intermediates are in the roll configuration the cohesive from one intermediate does not engage the cohesive from another. Preferably the cohesive patterns on one face of the intermediate are spaced from the parallel cohesive patterns on the second face of the intermediate by about 1-15 mm, preferably about one centimeter. Transversely extending patterns of cohesive also may be positioned so that they too do not engage in the roll configuration, even though engagement of the transverse patterns is much less of a problem because the potential areas for engagement are few when the intermediates are in the roll configuration.

Patent CA-2245359-A1 (CA)
Title: Pressure modulation valve assembly
Inventor: FINCHER ROGER W
IPC: E21B4/00
Filed: 1998-08-19
Abstract: A drillstring pressure-modulation valve is disclosed which is usable in combination with a downhole drilling motor and a drillstring thruster to compensate for changes in pressure drop through the drilling motor which normally occur during drilling.  When conditions chnage during drilling, which in turn changes the pressure drop through the drilling motor, the drillstring pressure-modulation valve compensates for such changes to minimize the effect of such changes on the operation of the thruster and the resulting WOB created by the thruster. The modulation valve has a feature which allows it to find automatically a balanced preload condition for the main needle valve, the primary functional element within the modulation valve, each time the rig pumps are turned off and then turned on. The modulation valve is fully self-contained, and is assembled as part of the bottomhole assembly. The device senses the no-load pressure drop in the system and sets itself each time the rig pumps are turned on to compensate for any change in the no-load pressure drop experienced below the device which could be attributable to such things as motor wear, bit nozzle plugging, or changes in the flow rate.  Accordingly, the hydraulic thrusting force remains constant over a wide range of drilling environments. As the drilling conditions change and the pressure drop in the downhole motor increases, the needle valve shifts to compensate for such additional pressure drop with a resultant small or no effect on the thruster and the resulting WOB created by the thruster located upstream of this modulation valve.
